Im hooking up 2 898c HD SI.s. I have ordered a 5 port ethernet switch and all cables that I need from Humminbird, which will be in this week. When I get everything all hooked up I will be running seperate transducers to each unit. Im going to share the console GPS with the bow unit. I will also have my Terrova I Pilot Link hooked in to the ethernet switch. All of this seems simple enough. My question is when I get everything hooked up can I put the 898 units into simulator mode to set all the network settings or do I need to have it in the water to setup. Im sure the transducers will be grayed out during simulation but will they be selectable will the GPS show up etc. I hope Im making sense.
